Systems We Install
We service and install all major makes and models for the following systems in Fairfax:
Gas and Electric Furnaces
Whether your property relies on a traditional natural gas line or an electric configuration, we keep your furnace running safely. We handle everything from repairing broken ignitors, faulty gas valves, and failing blower motors to conducting detailed carbon monoxide safety inspections and heat exchanger tests. When it is time for an upgrade, we install energy-saving single-stage, two-stage, or modulating variable-speed furnaces from top brands like Trane and Carrier to maximize your winter efficiency.
Hybrid and Central Heat Pumps
As versatile systems that handle both winter heating and summer cooling, heat pumps require specialized technical expertise. Our team quickly diagnoses and resolves stuck reversing valves, refrigerant leaks, electrical failures, and auxiliary heat strip malfunctions. We also provide comprehensive seasonal cleanings to keep your system running cleanly, and we install advanced modern heat pumps—including dual-fuel hybrid configurations that pair a heat pump with a gas furnace for the most cost-effective performance.
Ductless Mini-Splits
Ductless systems offer the perfect solution for custom zoned comfort, property additions, or homes lacking traditional ductwork layouts. As an official Mitsubishi Diamond Contractor, we provide elite-level design, installation, and service for multi-zone and single-zone configurations. We maintain your system with deep-cleaning services and quickly fix common issues like condensate line leaks, sensor malfunctions, and individual room zone control errors to keep every area of your home perfectly balanced.
Central Air Handlers
Your heating equipment cannot warm your home effectively without a properly functioning air handler to move the air. We offer complete service to resolve restricted airflow, broken fan belts, and burned-out fan motors that cause uneven hot and cold spots. Our technicians lubricate moving parts, inspect electrical connections during routine maintenance, and perform precision replacements to ensure your air handler is perfectly matched to your heat pump or furnace for peak factory efficiency.

Frequently Asked Questions
Frequently Asked Questions for Fairfax Homeowners
What are the most common signs my heating system needs emergency repair during a Fairfax winter?
You should call for service immediately if you notice cold air blowing from your vents during a freezing Northern Virginia cold snap, constant system short-cycling, or loud banging and rattling noises coming from your utility room. Sudden spikes in your Fairfax County utility bills or strange, musty odors when the system cycles on are also clear signs of an underlying mechanical issue.
Why is my heater running but blowing cold air?
This symptom can be caused by a faulty ignition system, a broken heating element, a failed thermocouple, or a malfunctioning heat pump reversing valve. Before scheduling a technician, verify that your thermostat is set to “Heat” rather than “Fan Only,” and check that your air filter isn’t completely clogged with dust.
What does it mean if my furnace is short-cycling or turning off too quickly?
Short-cycling is frequently caused by a dirty air filter restricting airflow, which triggers the system’s safety limit switch to shut down to prevent dangerous overheating. It can also point to a faulty thermostat, failing flame sensors, or an incorrectly sized heating system that warms the space too rapidly for your property layout.
Do you install and service heat pumps and ductless mini-splits in older Fairfax homes?
Absolutely. We have decades of experience adapting modern heating technology to regional property styles. Whether you want to retrofit an energy-efficient heat pump into an established home or resolve stubborn hot and cold spots using a Mitsubishi ductless mini-split, we design custom configurations tailored to your specific architectural layout.
Does replacing a gas furnace or heat pump require a municipal permit in Fairfax?
Yes. Under the Virginia Residential Code and local Fairfax County and Fairfax City guidelines, replacing mechanical heating equipment—especially gas-fueled furnaces—requires a proper mechanical or gas permit. When you choose Falcon Heating & Air Conditioning, our team handles the compliance paperwork and municipal requirements so your installation is fully legal, safe, and up to code.
How long does a standard furnace or heat pump installation take?
Most standard residential heating replacements throughout the Fairfax area are completed in one business day. Our installation teams arrive early in the morning with all necessary equipment, complete the installation, safety-test the new configuration, and entirely clean up the work area before leaving your home.
What brands of heating systems are you certified to service and install?
Our NATE-certified field technicians are trained to service, repair, and maintain all major HVAC makes and models. For homeowners looking to upgrade or replace their system, we are an official Trane Comfort Specialist and an elite Mitsubishi Diamond Contractor, ensuring you receive top-tier equipment efficiency and factory-backed warranties.
